Effects of L-Ascorbic Acid on the Skin
Antioxidant Protection:
Neutralizes Free Radicals: L-ascorbic acid neutralizes free radicals generated by UV exposure, pollution, and other environmental stressors. Free radicals can cause oxidative stress, leading to premature skin aging and damage.
Reduces Oxidative Stress: By reducing oxidative stress, L-ascorbic acid helps protect the skin from cellular damage, maintaining its health and appearance.
Collagen Synthesis:
Boosts Collagen Production: L-ascorbic acid is essential for collagen synthesis. It acts as a cofactor for enzymes involved in the hydroxylation of proline and lysine, amino acids necessary for collagen stability and strength.
Improves Skin Elasticity: Enhanced collagen production helps improve skin firmness and elasticity, reducing the appearance of fine lines and wrinkles.
Photoprotection:
Enhances UV Protection: L-ascorbic acid provides some photoprotection by neutralizing free radicals generated by UV radiation. When used in conjunction with sunscreen, it can enhance the protective effects against UV damage.
Reduces Sunburn Cell Formation: It minimizes the formation of sunburn cells, which are markers of UV-induced skin damage.
Brightening Effect:
Inhibits Melanin Production: L-ascorbic acid inhibits the enzyme tyrosinase, which is involved in melanin production. This helps reduce hyperpigmentation and dark spots, leading to a more even skin tone.
Promotes Radiance: Regular use of L-ascorbic acid can result in brighter, more radiant skin.
Anti-Inflammatory Properties:
Reduces Inflammation: L-ascorbic acid has anti-inflammatory effects, which can help soothe irritated skin and reduce redness. This is particularly beneficial for conditions like acne and rosacea.
How to Use L-Ascorbic Acid for Skin
Form and Concentration:
Topical Solutions: L-ascorbic acid is commonly found in serums, creams, and lotions. Serums are particularly effective as they are more concentrated and penetrate the skin easily.
Concentration: Effective concentrations of L-ascorbic acid in skincare products typically range from 5% to 20%. Higher concentrations may provide more noticeable results but can also cause irritation in sensitive skin.
Application Method:
Cleanse: Start with a clean face. Use a gentle cleanser to remove impurities and a toner to balance the skin’s pH.
Apply Serum: Apply a few drops of L-ascorbic acid serum to the face and neck, gently pressing it into the skin. It’s best to use it in the morning to take advantage of its protective properties against UV damage.
Follow with Moisturizer: After the serum has absorbed, apply a moisturizer to lock in hydration and provide a barrier to protect the skin.
Sunscreen: Always finish with a broad-spectrum sunscreen during the day. L-ascorbic acid can make the skin more sensitive to sunlight, so adequate sun protection is essential.
Storage and Stability:
Protect from Light and Air: L-ascorbic acid is unstable and can degrade when exposed to light and air. Store products in opaque, airtight containers to maintain their efficacy.
Refrigeration: Storing L-ascorbic acid products in the refrigerator can help extend their shelf life and preserve their potency.
Frequency of Use:
Daily Use: For best results, incorporate L-ascorbic acid into your daily skincare routine. Start with a lower concentration if you have sensitive skin and gradually increase as your skin builds tolerance.
Combination with Other Ingredients:
Vitamin E and Ferulic Acid: These antioxidants can stabilize L-ascorbic acid and enhance its efficacy, providing synergistic benefits for the skin.
Hyaluronic Acid: Combining L-ascorbic acid with hyaluronic acid can boost hydration and improve skin texture.
Potential Side Effects and Precautions
Irritation: Some people may experience skin irritation, redness, or a tingling sensation when using L-ascorbic acid, especially at higher concentrations. If this occurs, reduce the frequency of use or switch to a lower concentration.
In summary, L-ascorbic acid is a versatile and effective ingredient in skincare that offers antioxidant protection, boosts collagen synthesis, provides photoprotection, brightens the skin, and reduces inflammation. When used correctly, it can significantly improve skin health and appearance.
However wonderful L-ascorbic acid is, as we know if is not for everyone. We here random things like; I am allergic to it or it irritates me, this isn't true. This is due in the main to giving it to the wrong candidate, compromised skin, dehydrated or sensitised.
There is another option though that is safe for all skin types.
Tetrahexyldecyl Ascorbate (THD)
What is Tetrahexyldecyl Ascorbate?
Tetrahexyldecyl Ascorbate (THD Ascorbate) is an ester of ascorbic acid (vitamin C) and isooctyl (a branched chain of carbon atoms). This modification makes it different from the traditional water-soluble forms of vitamin C like L-ascorbic acid. The lipid-soluble nature of THD Ascorbate allows it to be more easily incorporated into oil-based formulations and to penetrate the skin more effectively.
Benefits of Tetrahexyldecyl Ascorbate
Enhanced Stability:
Less Prone to Oxidation: THD Ascorbate is more stable than L-ascorbic acid, making it less prone to oxidation and degradation when exposed to light, air, and heat. This stability extends the shelf life of skincare products containing this ingredient.
Improved Skin Penetration:
Lipid-Soluble: Being lipid-soluble, THD Ascorbate can penetrate the lipid-rich layers of the skin more efficiently than water-soluble forms of vitamin C. This enhances its effectiveness in delivering the benefits of vitamin C deeper into the skin.
Potent Antioxidant:
Neutralizes Free Radicals: Like other forms of vitamin C, THD Ascorbate acts as a powerful antioxidant, neutralizing free radicals generated by UV exposure, pollution, and other environmental stressors. This helps protect the skin from oxidative damage and premature aging.
Collagen Synthesis:
Stimulates Collagen Production: THD Ascorbate promotes the synthesis of collagen, which helps maintain the skin’s firmness and elasticity. This can reduce the appearance of fine lines and wrinkles.
Skin Brightening:
Reduces Hyperpigmentation: It inhibits the production of melanin, the pigment responsible for dark spots and uneven skin tone. Regular use of THD Ascorbate can result in a brighter, more even complexion.
Anti-Inflammatory Properties:
Soothes the Skin: THD Ascorbate has anti-inflammatory effects that can help reduce redness and irritation, making it suitable for sensitive skin.
How to Use Tetrahexyldecyl Ascorbate in Skincare
Formulations:
Serums and Creams: THD Ascorbate is commonly found in serums, creams, and lotions. These formulations allow for effective delivery of the active ingredient to the skin.
Concentration: Effective products typically contain THD Ascorbate at concentrations ranging from 1% to 20%. Lower concentrations may be suitable for sensitive skin, while higher concentrations can provide more significant results.
Application Method:
Cleanse: Start with a clean face. Use a gentle cleanser to remove impurities and a toner to balance the skin’s pH.
Apply Serum or Cream: Apply a few drops of a THD Ascorbate serum or a small amount of cream to the face and neck, gently pressing it into the skin.
Follow with Moisturizer: After the THD Ascorbate product has absorbed, apply a moisturizer to lock in hydration and provide a protective barrier.
Sunscreen: If used in the morning, always follow with a broad-spectrum sunscreen. This helps protect the skin from UV damage and complements the antioxidant protection provided by THD Ascorbate.
Frequency of Use:
Daily Use: For optimal results, incorporate THD Ascorbate into your daily skincare routine. Consistent use can lead to cumulative benefits over time.
Combination with Other Ingredients:
Vitamin E and Ferulic Acid: Combining THD Ascorbate with other antioxidants like vitamin E and ferulic acid can enhance its stability and efficacy.
Hyaluronic Acid: Using THD Ascorbate in conjunction with hyaluronic acid can boost skin hydration and improve overall skin texture.
Vitamin A: Unlike l-ascorbic acid THD can be mixed with Vitamin A as a nighttime treatment. Vitamin A and C love each other, but using l-ascorbic acid would cancel each other out THD doesn't so it works beautifuly.
Potential Side Effects and Precautions
Minimal Irritation: THD Ascorbate is generally well-tolerated and less likely to cause irritation compared to other forms of vitamin C, making it suitable for sensitive skin.
Conclusion
Tetrahexyldecyl Ascorbate is a highly effective and stable form of vitamin C that offers numerous benefits for the skin, including enhanced penetration, antioxidant protection, collagen synthesis, and skin brightening. Its lipid-soluble nature makes it a valuable ingredient in modern skincare formulations, suitable for a wide range of skin types and concerns.
